IPC: B61L3/24

Abstract: 1,257,756. Signalling system. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 30 June, 1970 [1 July, 1969], No. 31703/70. Heading B7N. In a track circuit and train control signalling system, each track circuit is fed with an A.C. signal and a high-amplitude pulse train synchronized with the A.C. signal such that the control information is represented by the number of signal cycles between pulses. On the train the information is decoded using the A.C. signal as clock pulses and at the track circuit entry point the A.C. signal controls the track circuit relay and the information is decoded to control the signals supplied to the preceding circuit. At the transmit end of the circuit A.C. generator E supplies the A.C. signal directly to the track circuit at winding L1 and also to the coding arrangement C which supplies the pulse signals to winding L2 spaced at a number of A.C. cycles representing the information e.g. train speed &c. On the train the signals are picked up by coils C1, C2 and separated by unit FA whereby the A.C. signals are amplified by unit Ap and the pulse signals by unit AS. The pulse signals are applied to amplifier G and also to the input I of a shift register R which is supplied at its input H with clock pulses from unit AP at the A.C. signal frequency. The shift register is formed with outlets at specific stages P 1  ... P n  each spaced from the input by a number of stages equal to the number of A.C. cycles between pulses for a specific item of information. Thus for a first item of information the first pulse will be stepped through the register and be at stage P 1  when the second pulse is supplied to its input by unit As. These two pulses are coincident at the inputs of gate ET 1  and this supplies an output to trigger oscillator O 1  which charges capacitor C via OR gate OU to a value which is a function of the signal delay between register input and stage P 1 . Oscillator 1 operates until capacitor C is discharged and during this period cuts off oscillators 2 and 3. The discharge is completed before the arrival of the 3rd pulse so that oscillator 3 provides a supply to amplifier G to pass this 3rd pulse to gate ET 1  where it coincides with the appearance of the 2nd pulse at stage P 1  to repeat the above process. In addition oscillator 2 supplies a signal to one input of gate ET<SP>1</SP> 1  which is also supplied with the 2nd pulse from stage P 1  to provide the information signal to display device AF 1  for the 1st item of information. Each item of information has associated therewith a stage P of the register, a pair of gates ET, ET<SP>1</SP>, an oscillator O and a display device AF.

Abstract: 1289251 Bi-stable logic circuits HONEYWELL INFORMATION SYSTEMS ITALIA SpA 10 May 1971 [8 May 1970] 14077/71 Heading H3T A bi-stable consists of AND gates 2, 3, 4, a NOR gate 5, and an inverting stage such as a NAND gate 8, all interconnected as shown and receiving a data signal D, and a control signal C, and its inverse which may be obtained by inverter 1. When D is high and the control (clock) C goes high, AND 4 causes NOR 5 to give a low output Q. This causes NAND 8 to give a high output Q, because R is normally high. Q enables AND gates 2, 3 so that until C ends, AND 3 maintains reciprocal coupling; and when C ends and the output of inverter 1 goes high, AND 2 maintains the reciprocal coupling. A low input to R resets independently of C and D. The NAND 8 may be alternatively a NOR (9, Fig. 4, not shown) with a normally low input, or it may be a simple inverter (6, Fig. 2, not shown). Diode transistor logic is used (Figs. 6, 7, not shown) or transistor-transistor logic (Fig. 8, not shown); and a shift register uses a plurality of the bistables (Fig. 5, not shown) having common C and R inputs.

The plenum chamber and baghouse chambers are divided into an equal number of compartments by partitions 14 and 12. The baghouse chamber compartments contain several filter bags 8 which are suspended from a support plate 10 (Fig. 4) which forms the bottom of the plenum chamber. Dirty gas enters through conduit 40 and is first deflected downward into hopper 6 and then rises into the baghouse chamber. Cleaned gas leaves the plenum chamber compartments through conduit 36 via poppet valves such as 30, 32 in each plenum compartment. When it is required to clean accumulated dust from the filters each poppet valve is closed in turn stopping the exit of cleaned gas from that plenum compartment, a short reverse flow burst of high pressure air is then admitted to the respective plenum chamber. The cleaning cycle may be initiated by means of a preset timer or by means of a relay switch sensitive to pressure drop across the flitter bags. Each compartment of the plenum chamber has doors 16 for internal access.

The dispersion may also contain polypropylene glycol in a proportion of 30 to 100% based on the weight of the polyamino salt. The finish is of general utility for the finishing of thermoplastic textile materials prone to wet-creasing, i.e. materials which tend to crease when dried in a relaxed condition. The heat-setting of polycaproamide materials requires a minimum temperature of 190‹C and a heat treatment of more than 20 seconds and usually less than 40 seconds. The polyamine fragment of the finish is exemplified by poly (N-alkyl ethylene imine), poly(N,N-dimethyl-#- amino ethyl acrylate) and poly(N,N-dimethyl- #-ethyl methacrylate) and quaternised derivatives of these. Examples of the polyacid fragment of the finish are homologues of succinic acid, phosphonic acid, a disulphonic acid of an aromatic compound or a maleinised siccative acid.

Abstract: 1341081 Lasers NORTHROP CORP 8 Nov 1971 51815/71 Heading H1C In a carbon monoxide laser the active medium includes mercury vapour which may be introduced by striking the pumping discharge of the laser between two pools of mercury, or by using one pool and a conventional pin electrode, or by passing the active medium through a mercury discharge before it reaches the laser resonator. The active medium basically comprises CO, N 2  and He, the mercury vapour serving to reduce mean electron energies and hence to favour the excitation of the N 2  and in turn the CO. Xenon and oxygen may also be added to raise the efficiency. In Fig. 1 (not shown) the discharge tube contains two pools of mercury which serve as pumping electrodes; such electrodes have a long life as well as introducing the vapour. In Fig. 2 a transverse discharge is used between pin electrode 45 and mercury 49. In Fig. 3 the basic medium flows in duct 63, through a discharge between pins 65 and mercury 67, through Venturi 69 and into chamber 71 where it lases between mirrors 73, 75 before exhausting along duct 77.
